For many company directors, a pension is the most tax-efficient way to take value out of their business: employer pension contributions are usually an allowable expense for the company, they do not attract employer National Insurance, and they build up retirement savings outside the company.
This guide explains pension contributions through your limited company: the tax relief, the £60,000 annual allowance, carrying forward unused allowance, and how pensions fit alongside salary and dividends.
How Pension Contributions Through Your Limited Company Work
When your company pays into your pension, the contribution is treated as a business expense — provided it passes the wholly and exclusively test, meaning the payment must be made wholly and exclusively for the purposes of the company’s trade. For a director who works in the business, contributions are normally accepted as allowable, although very large contributions can attract questions from HMRC.
The contribution is paid by the company, not by you personally. It does not count as salary, so no Income Tax is charged on it when it goes in, and no employer National Insurance is due on it either. You pay tax only when you draw the pension in retirement.
Tax Relief: The Company Saves Corporation Tax
Because the contribution is an allowable expense, it reduces the company’s taxable profit and the Corporation Tax it pays — for a company at the 25% main rate, a £10,000 contribution saves £2,500. Our guide to corporation tax marginal relief explains how the rates work.
There is an important timing rule: the contribution must actually be paid before the company’s year end for relief to be given in that accounting period. A contribution promised but not paid does not count. Pension contributions through your limited company only get relief in the period in which they are actually paid.
No Employer National Insurance on Pension Contributions
One of the biggest advantages is that employer pension contributions do not attract employer National Insurance — salary, by contrast, carries employer National Insurance on top of the pay itself.
That is why directors often prefer a mix of a modest salary and pension contributions: for every £1,000 paid as salary, the company pays employer National Insurance on top; for every £1,000 paid into a pension, it does not.
The £60,000 Annual Allowance
There is a limit on how much can be paid into your pension each tax year with tax relief: the annual allowance, currently £60,000. The allowance covers all pension contributions made for you in the tax year — employer contributions, personal contributions and any contributions from other sources. Pension contributions through your limited company count towards the £60,000 annual allowance.
If total contributions exceed the annual allowance, the excess is charged to Income Tax through your Self Assessment return, so plan around the limit.
Carrying Forward Unused Allowance
If you have not used your full annual allowance in earlier years, you may be able to carry forward the unused amount from the previous three tax years. This can be useful if your company has had a particularly profitable year and you want to make a larger contribution.
To use carry forward, you must have been a member of a registered pension scheme in each of those years, and you must use the current year’s allowance first.
Tapering for Very High Earners
For very high earners, the annual allowance is tapered down and can fall as low as £10,000. The rules are complex, so this is an area to take advice on: if your income is high, check your tapered allowance before making a large contribution.
Salary Sacrifice in Brief
Salary sacrifice is an arrangement where an employee gives up part of their salary in exchange for a pension contribution from the employer. The sacrificed salary is not subject to Income Tax or National Insurance, and the employer contribution is not subject to employer National Insurance either.
Salary sacrifice can work well, but it must be agreed in advance, it cannot take pay below the National Minimum Wage, and it can affect benefits that depend on salary. Take advice before setting it up.
Pensions Alongside Salary and Dividends
Most directors take a mix of salary, dividends and pension contributions, because each is taxed differently: salary is deductible for the company, dividends are taxed at dividend rates, and pension contributions get Corporation Tax relief with no employer National Insurance. Pension contributions through your limited company sit alongside salary and dividends in the mix.
The right mix depends on your income, your company’s profits and your retirement plans. Many directors take a salary up to the personal allowance, dividends up to the amount the company can afford, and pension contributions to use the annual allowance — see this guide to dividend tax rates in the UK for the dividend side.
Whether to run the business as a sole trader or a limited company also affects how pensions work — a sole trader’s contributions come from personal income, not from a company. See this guide to sole trader vs limited company tax.
Workplace Pensions for Your Staff
If you employ staff, pension contributions are not only for directors: under auto-enrolment, most employers must enrol eligible staff into a workplace pension and contribute towards it, and those contributions are also an allowable expense with no employer National Insurance. Our guide to PAYE and payroll basics explains the duties in brief.
Practical Steps
- Check your annual allowance — how much of the £60,000 you have used, and whether you have unused allowance to carry forward.
- Pay before the year end, so relief is given in that period.
- Keep records of every contribution, the date paid and the scheme it went to.
- Review the mix each year as your profits and income change.
